Question

An object has two million more electrons than protons. What is the net charge of the object?
C??

the asked answer in C

thanks

Answer 1

net charge "Q" is the difference between all positive and negative charges in the object.

electrons-protons=2,000,000

the charge every electron inherantly possesses is e=-1.60217646 × 10^-19coulombs

using this information you can say Q= e*2,000,000 for your answer.

Answer 2

the object has more electrons than protons this means that the net charge is negative.
The charge a electron is -1.602×10^-19C so if we have 2,000,000 of them multiply

(-1.602×10^-19C)x(2,000,000)= -3.204×10^-13C

this is the net charge of the object. Note is negative.
